In this research project, we will study the genetic determinants that influence the pharmacokinetics of antiretroviral drugs used in the treatment of diseases caused by the HIV.

Detailed Description:

The development of new active substances is a continuous source of progress in pharmacotherapy. However, the search for an optimal use of existing molecules constitutes another possible way of progress. In the particular field of anti-infectious therapy, an optimization of treatments could minimize the emergence of resistance phenomena that require the continuous development of new active molecules.

Pharmacogenetics is the scientific discipline seeking to improve the response to drug therapies (better clinical efficiency and reduction of side effects) by taking into consideration the genetic characteristics of the patient. Drugs with a narrow therapeutic index constitute a main target of this emerging field. The combination of therapeutic drug monitoring and pharmacogenetics already allows to optimize the use of some drugs among which oral anticoagulants, immunosuppressants, antiepileptics, antidepressors, antibiotics or antivirals….

In this research project, we will study the genetic determinants that influence the pharmacokinetics of antiretroviral drugs used in the treatment of diseases caused by the HIV. We will put a particular emphasis on viral protease inhibitors (atazanavir, saquinavir, lopinavir, ritonavir)and non-nucleosides reverse transcriptase inhibitors (nevirapine and efavirenz). For those drugs, the clinician often faces a double therapeutic risk, either of insufficient dosing (clinical inefficacy and emergence of resistance) or of excessive dosing (toxicity). The optimization of drug dosing is especially crucial because some of these drugs often represent the last choice in multi-resistant patients.
